BACKGROUND: Atrial fibrillation occurs frequently after open-heart surgery. It is associated with increased morbidity and mortality, longer hospital stays, and increased healthcare costs. Prophylactic administration of colchicine may mitigate post-operative atrial fibrillation (POAF). METHODS: We searched PubMed, ClinicalTrials.gov and CENTRAL databases to identify randomized controlled trials (RCTs) that; (1) compared prophylactic use of colchicine to placebo, or usual care, in patients with sinus rhythm who underwent elective open-heart surgery and (2) reported POAF-incidence...

Cardiac computed tomography angiography (CCTA) is a noninvasive imaging technique that has been rapidly adopted into clinical practice. Over the past decade, technological advances have improved CCTA accuracy, and there is an increasing amount of data supporting its prognostic value in the assessment of coronary artery disease. Recently, "appropriate use criteria" has been used as a tool to minimize inappropriate testing and reduce patient exposure to unnecessary risk and inconclusive studies. This review will summarize the appropriate uses of CCTA in patients before and after cardiac surgery...

The ability of the adult heart to regenerate cardiomyocytes (CMs) lost after injury is limited, generating interest in developing efficient cell-based transplantation therapies. Rigid carbon nanotubes (CNTs) scaffolds have been used to improve CMs viability, proliferation, and maturation, but they require undesirable invasive surgeries for implantation. To overcome this limitation, we developed an injectable reverse thermal gel (RTG) functionalized with CNTs (RTG-CNT) that transitions from a solution at room temperature to a three-dimensional (3D) gel-based matrix shortly after reaching body temperature...

BACKGROUND: Among patients undergoing non-cardiac surgery, major vascular surgery is associated with a high risk of perioperative myocardial infarction (MI). Currently there are no perioperative MI risk calculators accounting for intraoperative and postoperative risk factors in vascular surgery patients. We aimed to investigate specific risk factors for perioperative MI after major open vascular surgery to determine which patients are at highest risk of MI, and the association of perioperative MI with perioperative transfusion...

OBJECTIVE: We sought to evaluate the risk and image quality from cardiovascular CT in patients across all stages of single-ventricle palliation, and to define accuracy by comparing findings with intervention and surgery. METHODS: Consecutive CT scans performed in patients with single-ventricle heart disease were retrospectively reviewed at a single institution. Diagnosis, sedation needs, estimated radiation dose, and adverse events were recorded. Anatomical findings, image quality (1-4, 1=optimal), and discrepancy compared with interventional findings were determined...

BACKGROUND: Tranexamic acid (TXA) is commonly administered during on-pump cardiac surgery to minimize bleeding. However, an optimal dosing regimen has not been described, and recent studies suggest that higher doses may be associated with seizure. Little is known about current practice among cardiac anesthetists. METHODS: We contacted all academic anesthesia departments in Canada to identify cardiac anesthetists, who represent the majority of practitioners. This group constituted our sampling frame...

BACKGROUND: Induction of anaesthesia causes significant macrohaemodynamic changes, but little is known about its effects on the microcirculation. However, alterations in microvascular perfusion are known to be associated with impaired tissue oxygenation and organ dysfunction. Microvascular reactivity can be assessed with vascular occlusion testing, which evaluates the response of tissue oxygen saturation to transient ischaemia and reperfusion. OBJECTIVE: The aim of the current study was to evaluate the effects of an opioid-based anaesthesia induction on microvascular reactivity...

Despite great progress in engineering functional tissues for organ repair, including the heart, an invasive surgical approach is still required for their implantation. Here, we designed an elastic and microfabricated scaffold using a biodegradable polymer (poly(octamethylene maleate (anhydride) citrate)) for functional tissue delivery via injection. The scaffold's shape memory was due to the microfabricated lattice design. Scaffolds and cardiac patches (1 cm × 1 cm) were delivered through an orifice as small as 1 mm, recovering their initial shape following injection without affecting cardiomyocyte viability and function...

Terumoto Koike, Masanori Tsuchida
For general thoracic surgeons, perioperative management for prevention of cardiac complications is important because patients undergoing general thoracic surgery often have risk factors for cardiac disease. Sever cardiac failure should be detected and treated prior to surgery, and coronary artery may be examined in patients with risk factors for ischemic heart disease. Pulmonary resection sometimes causes right-sided heart failure due to reducing pulmonary vascular bed. In high-risk patients for rightsided heart failure, pulmonary artery pressure monitoring by right heart catheterization should be considered in addition to blood pressure and central venous pressure monitoring, and precise fluid management is required...

Chronic kidney disease(CKD) is an important risk factor of open heart surgery. In addition, worsening of kidney function after the surgery leads to poor prognosis long-term. It is therefore crucial to protect the kidney function by intensive perioperative management in open heart surgery. In the patients having stage 3-4 CKD, mean arterial pressure needs to be higher than 70 mmHg and cardiac index needs to be greater than 2.4 intraoperatively and postoperatively. Continuous right heart monitoring by Swan-Ganz catheter is useful for this purpose...

BACKGROUND: Laparoscopic local gastric resection has become the standard form of surgery for gastric submucosal tumors (SMTs) and is currently being actively selected for these cases. However, total gastrectomy or proximal gastrectomy is performed when tumors are adjacent to the cardia of stomach. Unfortunately, these procedures are highly invasive and can cause marked decreases in activities of daily living. We perform a single-incision laparoscopic intragastric surgery (sLIGS), which are both minimally invasive and offers improved cosmetic outcomes, to treat SMT located adjacent to the esophagogastric junction (EGJ)...
